Lets see the EGTs output from 2-5k at WOT, if the K03 really is making 260bhp / 310lbft with OEM down pipe inc. pre-cat brick wall and 800 cell cat... Then it's either... Not a TFSI but A TSI motor in which case not a K03, Or There is exhaust development, or the figures are to be taken with a pinch of saline.
